Abstract: Aiming at the shorthand of unmanned undersea vehicle (UUV) with poor endurance, combining with the technology of heat pipe reactor with silent thermoelectric conversion, a non-nuclear electric heating experiment platform is established to conduct the start -up experiment. Experiment results show that, the experimental start-up process is smooth, the isothermality is good after the start-up. The thermoelectric performance of the thermoelectric generator is good, with the efficiency of 6.8%. As the first electric heating experiment platform based on thermoelectric power generation and high temperature heat pipe heat transfer, the experimental data could provide a reference for the further design and application of the silent thermoelectric heat pipe reactor.
